A further object of the invention is to deviseY a novel arrangement ofan oven vent damper and fuel supply control for the broiling and bakingburners of the oven, wherein the operating handle of the fuel valve isfirst longitudinally moved to open the -vent damper and interlock withthe valve cock. The valve handle can then be turned in one direction tosupply fuel to the baking burner or in an opposite direction to supplyfuel to the broiler burner. When fuel is supplied to either burner theoven vent damper is open. The oven vent damper is returned to its closedposition by a spring.

With the abovev and other objects in view as will hereinafter clearlyappear, my 'invention comprehands novel controlling means for the ovenvent damper and for the supply of fuel to a baking or broiler burner ofthe oven, which is constructed and arranged to have the oven vent openwhen fuel is supplied to either burner.

Other novel features of construction and advantage will hereinafter moreclearly appear in the detailed description and the appended claims.

For the purpose of illustrating the invention, I have shown in theaccompanying drawings a typical embodiment of it, which, in practice,will give satisfactory and reliable results. It is, however,` to beunderstood that the various instrumentalities of which my inventionconsists can be variously arranged and organized and my invention is notlimited to the exact arrangement and organization of theseinstrumentalities as herein set forth.

Referring to the drawings:

The general construction of the dual range is substantially the same asthat shown in my Patent No. 2,089,816, of Aug. 10, 1937.

The fire pot of the range forms a combustion chamber I for a coal burneror an oil burner. The oven 2 is heated by products of combustion fromthe combustion chamber I or by a gas burner 3 which is the baking orheating burner' 15 of the oven.

The bottom 4 of the oven has spaced tubes or channels 5 extending, asshown, from the front to the rear of the oven and are directed upwardlyto discharge into the oven to form baiiies 20 6 extending over thedischarge openings 'I to prevent spillovers lodging in the tubes.

The gas burner 3 is in a channel 8 built around the outer edge of a coalgas iiue 9. The two side arms of the burner 3 burn upwardly in channels25 I0 extending preferably the entire depth of the oven. The front armof the burner 3 supplies` heat to the tubes 5. The flue gases pass fromthe oven through the oven vents II. Side openings I2 in the oven areconcealed by apertured-strips 30 I3 to which spaced runners I4 aresecured. A compartment I5 for top gas burners has its wall contributingwith the oven top to form a top coal gas flue I6 which leads to th'eside vertical coal gas flue II which leads to the bottom coal gas 35flue 9. 1

The burner 3 has a lighter opening I8 and air intakes I9 for secondaryair.

The vent opening II opens into an open ended casing 20, open ends ofwhich discharge into the 40 room in which the range is located. Thecasing 20 has discharge openings 2I to themain discharge iiue 22 andthese openings are controlled by a damper 23. The oven vents I larecontrolled by an oven vent damper 24 connected at 25 with 45 the damper23 so that they are both opened at the same time and are both closed atthe same time.

26 is a fuel supply. valve in the form of a twoway valve having a pipe21 leading to the bak- 50 ing burner 3 and a pipe 28 leading to abroiler burner 29 preferably located in the upper part of the oven. s

The fuel supply valve 26 has a handle 30 to which is connected a disc 3land a stem 32. When 55 the handle is pressed forwardly the disc 3|contacts with and moves forwardly a rod 33 which at its inner end isconnected at 34 with one end' of a lever 35 pivoted at 36 to the range.'I'he opposite end of the lever 35 is connected by a link 31 with oneend of a, lever 38 pivoted at 39. The opposite end of the lever 38 isconnected by a link 50 with the oven vent damper 24. The opposite end ofthe oven vent damper is connected with one end of a spring is connectedto a fixed portion of the range as at 4|.

The valve stem 32 has a collar 42 fixed to it and provided with a lug 43to pass through a slot 44 in an annular flange at the end of the bodyand be disposed beneath the flange and thereby retain a pin 45 on thecollar in a slot 46 at the outer end of the valve plug 41. When thevalve handle is turned the terlocked condition with the valve plug untilit is turned back to its neutral position. A spring 48 between the valveand stem will at such time move the valve stem outwardly, away from thevalve plug and the valve will bein its unlocked position. A shoulder 49on thevalve stem limits its inward movement.

It will now be apparent that when the valve handle is pressed forwardlythe disc 3| will move forwardly the rod 33 and thereby due to thelinkage and lever connections with the oven vent damper 24 move thelatter against the tension of its spring into its open position andthereby also the Idamper 23 into its open position. The valve stem isnow interlocked with the Valve plug so that the turning of the valvehandle in one direction or the opposite direction will supply fuel toeither the broiler or the over burner, as may be desired.

Since the handle and thereby the disc 3| is retained in its inwardlyposition when fuel is supplied to a selected burner, the oven ventdamper will be held in its open position during such period.

When however, the valve stem is unlocked from the valve, and moves toits outward position the spring 40 will close the oven vent damper andreturn its controlling linkage to its normal position.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is:

1. The combination with a wall of a range, of al'valve positionedinwardly of said Wall hav- 40 the opposite end of which stem is thusretained in in- Wall and ing a valve body, a valve plug and a valvestem, said valve stem extending through said wall and being normallydisconnected from said plug, said valve stem and plug havinginterlocking means to lock them together when the valve stem is movedtowards the valve plug, a spring between the valve stem and valve plug,a grasping handle for the valve stem, and a damper actuating memberactuated by said grasping handle prior to the interlocking of the valvestem with the valve plug when the valve stem is moved towards the valveplug.

2. The combination with a wall of a range, of a valve positionedinwardly of said wall having a valve body, a valve plug and a valvestem, said valve stem extending through said wall and being normallydisconnected from said plug, said valve stem and plug havinginterlocking means to lock them together when the valve stem is movedtowards the valve plug, a spring between the valve stem and valve plug,a grasping handle for the valve stem, and a longitudinally movabledamper actuating rod passing through said wall with an end in the pathof forward movement of the valve stem whereby said ro-d is moved beforethe valve stem can be interlocked with the valve plug.

3. The combination with a wall of a range, of a valve having a valvebody positioned inwardly of said wall, with a. valve plug provided atone end with openings, a valve stem having means to enter one of saidopenings when moved longitudinally of the valve body, a spring tendingto move said valve stem away from the valve body, a grasping handle forthe valve stem, and a damper actuating member in the path oflongitudinal movement of said grasping handle to be moved thereby priorto the means on the valve stem entering the opening of the valve plug toconnect such parts for rotation of the valve plug.

4. The combination with the wall of a range, of a valve mechanismpositioned inwardly of said having a. valve stem extending exterior ofsaid wall and normally disengaged from the valve of such valvemechanism, said stem and plug having means to interlock them on theirrelative longitudinal movement, a spring tending to cause the unlockingmovement of the valve stem, and damper actuating means actuated by theforward movement of the valve stem prior to the interlocking of saidvalve stem with the valve plug.
